In order to standardize the use of terminology in the new energy battery industry and avoid confusion between the concepts of "semi-solid state batteries" and "all solid state batteries" in the market, relevant regulatory authorities are preparing to introduce new policies to uniformly rename "semi-solid state batteries" as "solid-liquid batteries".
The naming adjustment aims to more accurately reflect the technical characteristics of such batteries, enhance industry transparency, and guide the public and investors to correctly understand the differences between different technological routes.
Solid liquid battery "(formerly" semi-solid battery ") is a transitional technology route between traditional liquid lithium batteries and all solid state batteries. Its core characteristics are:
1. The electrolyte system includes both solid electrolyte and liquid/gelled electrolyte;
2. Usually, some solid electrolytes are used to replace traditional liquid electrolytes, but a certain proportion of liquid phase substances are still retained to maintain ion conductivity;
3. Unlike the "completely liquid free" solid-state battery, solid-liquid batteries still have flowable or semi flowable electrolyte components in their structure.
1. Clarify the technological boundaries: clarify that "solid-liquid batteries" are not "all solid state" to prevent the generalization of technical concepts;
2. Guide rational expectations: avoid the public mistakenly believing that "semi-solid=solid" and reduce market speculation risks;
3. Promote technological development: While promoting the research and development of all solid state batteries, provide clear positioning for transitional technologies;
4. Standardize industry order: Uniform terminology helps with standard setting, product certification, and policy support.
As all solid state battery technology gradually moves from the laboratory to production line verification, it is increasingly important to clarify the boundaries of the technological path. The new name "solid-liquid battery" will more scientifically reflect its technological essence and promote the healthy and orderly development of the industry. In the future, solid-liquid batteries can serve as an important technological solution for transitioning to all solid state batteries, while true all solid state batteries still need to achieve breakthroughs in materials, processes, and costs.
